This study attempts to characterize the electromagnetic compromising emanations from Laser Facsimile. Electromagnetic radiation is inevitable when electronic equipment works. The radiations can deteriorate the performance of a part of device itself or of another system. This phenomenon is a subject in the field of electromagnetic compatibility (EMC). But concerning people who process classified information,...
Information might be leaked through electromagnetic radiation from a computer display. Radiation containing information and radiation without information should be treated differently. Therefore, a novel algorithm has been developed to determine whether or not information is leaked in electromagnetic radiation. Motivated by the observation that the Gabor coefficients of information part and the non-information...
The electromagnetic waves emitted from devices can be a source of information leakage and can cause electromagnetic compatibility (EMC) problems. Electromagnetic radiation signal from computer display can be seen as a computer security risk if the radiation signal is intercepted and reconstructed. In addition to the image information displayed by the computer, electromagnetic radiation leaks the hardware...
